4. Using whitening toothpastes daily
Whitening toothpaste can remove light surface stains on teeth caused by tobacco, and staining foods such as coffee and tea, but using them daily can actually make your teeth look worse. “Whitening toothpastes can be too abrasive, and if you use them every day they can lead to severe tooth wear,” says Albert. Many of these products contain abrasive particles or a compound called silica that will detrimentally remove the surface enamel of your teeth if they’re overused. “They can lead to tooth sensitivity, and ugly looking teeth because you’ve worn them down,” she says.
